Hydroxypropyl methylcellulose, yomwe imadziwika kuti HPMC, ndi yochokera ku cellulose yomwe imagwiritsidwa ntchito m'mafakitale osiyanasiyana kuphatikiza zakudya, zodzoladzola, mankhwala ndi zomangamanga. Ndizinthu zopanda fungo, zopanda pake komanso zopanda poizoni zomwe zimatha kugwira ntchito zosiyanasiyana monga kukhuthala, kumanga ndi kukhazikika.
HPMC imapezeka m'makalasi osiyanasiyana okhala ndi katundu ndi mikhalidwe yapadera kuti ikwaniritse zosowa zamitundu yosiyanasiyana. M'nkhaniyi, tikambirana mitundu yosiyanasiyana ya HPMC ndi ntchito zawo.
1.Pharmaceutical grade HPMC
Pharmaceutical grade HPMC ndi mkulu chiyero HPMC ntchito mu makampani mankhwala kupanga mapiritsi, makapisozi, mafilimu ndi zokutira. Amapangidwa motsatira njira zowongolera bwino kuti zitsimikizire chitetezo chake komanso kugwiritsa ntchito bwino anthu.
Pharmaceutical grade HPMC ili ndi ubwino wa viscosity controllable, zinthu zabwino kwambiri zopangira mafilimu, komanso kutentha kwa gelling. Ndiwogwirizana kwambiri ndi zosakaniza zina zamankhwala, zomwe zimapangitsa kuti zikhale zoyenera kuwongolera komanso kumasulidwa kokhazikika.
2. Chakudya kalasi HPMC
Gulu lazakudya HPMC ndi kalasi yopanda poizoni HPMC yomwe imagwiritsidwa ntchito m'makampani azakudya kuti kunenepa, kulimbitsa komanso kukhazikika chakudya. Zavomerezedwa ndi mabungwe osiyanasiyana owongolera zakudya kuphatikiza FDA, EFSA ndi FSSAI ngati zotetezeka kuti zigwiritsidwe.
Food grade HPMC imapezeka m'ma viscosities osiyanasiyana, kuyambira otsika mpaka apamwamba, kuti akwaniritse zosowa zamagulu osiyanasiyana a zakudya. Itha kugwiritsidwa ntchito muzakudya zosiyanasiyana monga zowotcha, mkaka, confectionery ndi zakumwa.
3. Zodzikongoletsera kalasi HPMC
Cosmetic grade HPMC ndi mtundu wapamwamba kwambiri wa HPMC womwe umagwiritsidwa ntchito m'makampani azodzikongoletsera chifukwa chokhuthala, kumanga komanso kukhazikika. Ndizoyenera pazinthu zodzisamalira nokha monga zonona, mafuta odzola, ma shampoos ndi ma gels.
Cosmetic-grade HPMC imapezeka m'ma viscosity osiyanasiyana ndipo imatha kuphatikizidwa mosavuta mumitundu yosiyanasiyana popanda kukhudza kukhazikika kwake kapena kapangidwe kake. Amapereka zodzoladzola zokhala ndi mawonekedwe osalala, a silky pomwe amawongolera kusunga kwawo madzi komanso kufalikira.
4. Zomangamanga kalasi HPMC
Architectural grade HPMC ndi kalasi yapadera ya HPMC yomwe imagwiritsidwa ntchito pantchito yomanga pazinthu zosiyanasiyana monga matope opangidwa ndi simenti, zomatira matailosi ndi ma grouts. Amagwiritsidwa ntchito ngati chosungira madzi kuti apititse patsogolo ntchito, kumamatira komanso kulimba kwa zida zomangira.
Kalasi yomanga HPMC imapezeka m'makalasi osiyanasiyana okhala ndi ma viscosity osiyanasiyana ndi katundu wa gel. Ndiwokhazikika kwambiri pansi pazikhalidwe zosiyanasiyana zachilengedwe monga chinyezi chambiri ndi kutentha, zomwe zimapangitsa kuti zikhale zabwino kwa ntchito zakunja.
5. Industrial grade HPMC
Industrial grade HPMC ndi gulu losunthika la HPMC lomwe lingagwiritsidwe ntchito m'mafakitale osiyanasiyana monga utoto, zokutira ndi zotsukira. Amagwiritsidwa ntchito ngati thickener, binder ndi stabilizer kupititsa patsogolo ntchito ndi khalidwe la mankhwala omaliza.
Industrial grade HPMC imapezeka m'makalasi osiyanasiyana okhala ndi ma viscosity apadera, mitundu ya pH ndi katundu wa gel kuti akwaniritse zosowa zamakampani osiyanasiyana. Zimagwirizana kwambiri ndi zowonjezera zamagulu osiyanasiyana, zomwe zimapangitsa kuti zikhale zabwino kwambiri pakupanga zovuta.
HPMC ndi zinthu zofunika m'mafakitale osiyanasiyana amafuna thickening, kugwirizana ndi kukhazikika katundu. Makalasi osiyanasiyana a HPMC ali ndi katundu ndi mawonekedwe apadera kuti akwaniritse zosowa zamitundu yosiyanasiyana. Kusankha giredi yoyenera ya HPMC kumatha kupititsa patsogolo magwiridwe antchito ndi mtundu wa chinthu chomaliza ndikuwonetsetsa kuti chitetezo chake ndi chothandiza pakugwiritsa ntchito anthu.
